Abstract: ETCHING SOLUTIONS CONTAINING AMMONIUM FLUORIDE AND ANIONIC SULFATE ESTERS OF ALKYLPHENOL POLYGLYCIDOL ETHERS     Abstract of the Disclosure An etching solution for use, for example, in the manufacture of integrated circuits is comprised of an aqueous solution of ammonium fluoride and a wetting amount of a sulfate ester of an alkylphenol polyglycidol ether or an alkyl amine glycidol adduct.  The etching solution preferably contains hydrogen fluoride in a volume ratio of NH4F to HF is from about 3:1 to about 100:1.           The novel etching solutions of the present invention all retain their wetting properties after 0.2 micron filtration, even under continuous filtration conditions.  Moreover, the etching solutions after filtering have the property of wetting substrates more effectively and yield more uniform results by etching small geometries (1 to 5 microns) and large geometries (> 5 micron) of silicon dioxide in a patterned resist at the same rate without additional deleterious effects. Further, the nonionic wetting agents do not incorporate metallic ions in their structure.

Abstract: The present invention is intended to solve the problem of the reliable acquisition of accurate temperature data for a miniature calculator provided for the application of family planning methods. The calculator is provided with a receptacle removably carrying a thermometric probe for providing the temperature measurement in a digital form. The circuits of the probe comprise an oscillator including a temperature responsive resistance element to be placed in contact with the area of the temperature to be measured, Tx. The output frequency fx of this oscillator is a function of Tx, and is measured by a counter controlled by a signal formed from a reference frequency fr provided by a reference oscillator and further provided to a frequency divider. A comparator compares the contents of the counter to that of a memory, and in case the counter contents is higher than the stored contents, the comparator controls the entry thereof to the memory so that the probe operates as a maximum thermometer. The contents of the memory is read in serial fashion by the system of the calculator when the probe is replaced into its receptacle.
